Definitions

  • the invention relates to a transducer winding of a transducer and a transducer.
  • the invention relates to transducers designed as voltage transformers.
  • Voltage transformers are available in single-pole or three-pole encapsulated versions, which are equipped with protective and measuring windings.
  • a voltage converter has a high-voltage winding and one or more secondary windings for measurement and protection purposes.
  • the high-voltage windings of voltage transformers are so far wound with very thin copper wires. Due to the winding speed during the high voltage winding manufacturing process, the thickness of the wires is determined not by the current carrying capability but mainly by the required mechanical strength. To produce the high voltage winding to use a very thin wire to keep the space required for the high number of turns of the winding low.
  • copper Due to its high electrical conductivity and its good mechanical processability, in particular its high tensile strength, copper is chosen as material for transducer windings. Furthermore, the invention relates to trained as a current transformer transducers. Current transformer cores are usually wound with copper wires.
  • the invention has for its object to provide a particularly improved in terms of material costs transducer winding of a transducer and a correspondingly improved transducer.
  • the object is achieved with respect to the transducer winding by the features of claim 1 and with respect to the transducer by the features of claim 5.
  • a transducer winding of a transducer according to the invention is made of an aluminum alloy containing at least one fullerene.
  • aluminum wire is mainly used for manufacturing reasons not for high voltage windings of voltage transformers, because of the high winding speed during the manufacturing process of a transducer winding thin wires would tear from the relatively brittle aluminum material. If you were to use conventional aluminum wire to produce a transducer winding, you would have to use due to the low tensile strength of aluminum wire, which is much thicker than copper wire and therefore would significantly increase the space requirement for the transducer winding.
  • the invention provides to reinforce aluminum by alloying with at least one fullerene and to use for the manufacture of a transducer winding.
  • Aluminum alloys with a low fullerene content have very good strength properties, so that the manufacturing speeds can be maintained when winding transducer coils, without having to increase the wire thickness unacceptable compared to copper wire, to prevent tearing of the wire in the manufacturing process.
  • the material copper used so far can be advantageously replaced by a much more favorable material, which has a similar good electrical conductivity as copper and also allows the production of transducer windings with very small wire thicknesses.
  • Preferred embodiments of the invention provide that the aluminum alloy contains the fullerene C 60 or / and the fullerene C 70 .
  • the fullerenes C 60 and C 70 are particularly advantageous as components of the aluminum alloy, since they particularly enhance the strength properties of the aluminum alloy and also increase the electrical conductivity compared to pure aluminum.
  • a further embodiment of the invention provides that a mass fraction of the at least one fullerene on the aluminum alloy is between 1% and 3%.
  • a mass fraction of fullerenes between 1% and 3% of the aluminum alloy is preferred because it has proven to be particularly advantageous for achieving the required strength properties of the aluminum alloy.
  • a transducer according to the invention has at least one transducer winding according to the invention.
  • At least one transducer winding of the transducer according to the invention is a high-voltage winding.
  • a further embodiment of a transducer according to the invention provides that at least one secondary winding of the Measuring transducer is designed as a transducer winding according to the invention.
  • This embodiment also advantageously leads to a reduction in the cost of manufacturing a transducer due to the reduction of material costs, when secondary windings are made of an aluminum alloy according to the invention instead of copper.
  • the conductivity improvement of the aluminum alloy by fullerenes has a particularly advantageous effect, since it makes it possible to reduce the thickness of the secondary winding wires in comparison to pure aluminum.
  • an aluminum alloy according to the invention is particularly suitable as material for secondary windings of current transformers.
  • An inventive transducer can accordingly be designed as a voltage converter or as a current transformer.
